Using ishRemote, how can I get the DITA OT log file contents in a Get-IshEvent request?

I dropped my question in the wrong forum, so I'm trying again :(

I wrote this little PowerShell routine to get the log for a specific event. I can get the detail, but I cannot figure out how to get the contents of the DITA-OT log file. Can you help me?

I tried looking at IshEventData for the DITAOTLogFile event but the byte array is 0 in length.

$targetServer = "xxxxxx"

if($ishSession -eq $null) {
$ishSession = New-IshSession -WsBaseUrl $targetServer
}

$requestedMetadata = Set-IshRequestedMetadataField -IshSession $ishSession -Name "EVENTID" -Level "Progress" |
Set-IshRequestedMetadataField -IshSession $ishSession -Name "EVENTTYPE" -Level "Progress" |
Set-IshRequestedMetadataField -IshSession $ishSession -Name "EVENTDATATYPE" -Level "Detail" |
Set-IshRequestedMetadataField -IshSession $ishSession -Name "DETAILID" -Level "Detail"

$metadataFilter = Set-IshMetadataFilterField -IshSession $ishSession -Name "DESCRIPTION" -Level "Progress" -FilterOperator Like -Value "Publish process for GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx=3=HTMLOutput=en-us"

$eventLog = Get-IshEvent -IshSession $ishSession -RequestedMetadata $requestedMetadata -EventTypes "PUBLISH" -MetadataFilter $metadataFilter

$eventLog
